History was made this morning at the International Space Station. On April 24, Peggy Whitson marked 534 days, two hours, and 49 cumulative minutes in space, earning her the record for longest time spent off the planet for a U.S. astronaut, Fortune reports.
Since launching her career with NASA in the 1980s, Whitson has racked up a list of accomplishments. The biochemist worked as NASA’s first science officer during her first trip to the International Space Station in 2002. She returned in 2008 as a commander, and on her most recent visit, she became the first woman to command the station twice. She also holds records for most spacewalks conducted by a woman (eight) and oldest woman in space at age 57.
Whitson began her third and current mission at the ISS on November 17, 2016. Prior to today, NASA’s record for most cumulative days spent in space was held by Jeff Williams, who took the title from Scott Kelly in August of last year.
Of the more than 12,800 hours Whitson has lived in space, 53 of them have been spent outside the station on spacewalks. Her total time will surpass 650 days when she concludes her mission in September.
Depending on where you live, the historic eclipse on August 21 might not look all that impressive from your vantage point. You may be far away from the path of totality, or stuck with heartbreakingly cloudy weather. Maybe you forgot to get your eclipse glasses before they sold out, or can't get away from your desk in the middle of the day.
But fear not. NASA has you covered. The space agency is live streaming a spectacular 4K-resolution 360° live video of the celestial phenomenon on Facebook. The livestream started at 12 p.m. Eastern Time and includes commentary from NASA experts based in South Carolina. It will run until about 4:15 ET.

4 Expert Tips on How to Get the Most Out of August's Total Solar Eclipse

As you might have heard, there’s a total solar eclipse crossing the U.S. on August 21. It’s the first total solar eclipse in the country since 1979, and the first coast-to-coast event since June 8, 1918, when eclipse coverage pushed World War I off the front page of national newspapers. Americans are just as excited today: Thousands are hitting the road to stake out prime spots for watching the last cross-country total solar eclipse until 2045. We’ve asked experts for tips on getting the most out of this celestial spectacle.
1. DON’T FRY YOUR EYES—OR BREAK THE BANK
To see the partial phases of the eclipse, you will need eclipse glasses because—surprise!—staring directly at the sun for even a minute or two will permanently damage your retinas. Make sure the glasses you buy meet the ISO 12312-2 safety standards. As eclipse frenzy nears its peak, shady retailers are selling knock-off glasses that will not adequately protect your eyes. The American Astronomical Society keeps a list of reputable vendors, but as a rule, if you can see anything other than the sun through your glasses, they might be bogus. There’s no need to splurge, however: You can order safe paper specs in bulk for as little as 90 cents each. In a pinch, you and your friends can take turns watching the partial phases through a shared pair of glasses. As eclipse chaser and author Kate Russo points out, “you only need to view occasionally—no need to sit and stare with them on the whole time.”
2. DON’T DIY YOUR EYE PROTECTION
There are plenty of urban legends about “alternative” ways to protect your eyes while watching a solar eclipse: smoked glass, CDs, several pairs of sunglasses stacked on top of each other. None works. If you’re feeling crafty, or don’t have a pair of safe eclipse glasses, you can use a pinhole projector to indirectly watch the eclipse. NASA produced a how-to video to walk you through it.
3. GET TO THE PATH OF TOTALITY
Bryan Brewer, who published a guidebook for solar eclipses, tells Mental Floss the difference between seeing a partial solar eclipse and a total solar eclipse is “like the difference between standing right outside the arena and being inside watching the game.”
During totality, observers can take off their glasses and look up at the blocked-out sun—and around at their eerily twilit surroundings. Kate Russo’s advice: Don’t just stare at the sun. “You need to make sure you look above you, and around you as well so you can notice the changes that are happening,” she says. For a brief moment, stars will appear next to the sun and animals will begin their nighttime routines. Once you’ve taken in the scenery, you can use a telescope or a pair of binoculars to get a close look at the tendrils of flame that make up the sun’s corona.
Only a 70-mile-wide band of the country stretching from Oregon to South Carolina will experience the total eclipse. Rooms in the path of totality are reportedly going for as much as $1000 a night, and news outlets across the country have raised the specter of traffic armageddon. But if you can find a ride and a room, you'll be in good shape for witnessing the spectacle.
4. PRESERVE YOUR NIGHT VISION
Your eyes need half an hour to fully adjust to darkness, but the total eclipse will last less than three minutes. If you’ve just been staring at the sun through the partial phases of the eclipse, your view of the corona during totality will be obscured by lousy night vision and annoying green afterimages. Eclipse chaser James McClean—who has trekked from Svalbard to Java to watch the moon blot out the sun—made this rookie mistake during one of his early eclipse sightings in Egypt in 2006. After watching the partial phases, with stray beams of sunlight reflecting into his eyes from the glittering sand and sea, McClean was snowblind throughout the totality.
Now he swears by a new method: blindfolding himself throughout the first phases of the eclipse to maximize his experience of the totality. He says he doesn’t mind “skipping the previews if it means getting a better view of the film.” Afterward, he pops on some eye protection to see the partial phases of the eclipse as the moon pulls away from the sun. If you do blindfold yourself, just remember to set an alarm for the time when the total eclipse begins so you don’t miss its cross-country journey. You'll have to wait 28 years for your next chance.
